Hey,
After installing my new AFE DPF delete exhaust kit, as soon as my truck heats up it starts to poor white smoke. At idle and take off its the worst. And now its showing a check engine code. All sensors are installed. Does anyone know how to remedy this?
Thanks

Umm, reinstall DPF?

Was the ecm reprogrammed to ignore DPF sensors? If not, maybe it is trying to regen all the time. Regen dumps fuel into the cylinders late in the cycle, it would blow on through unburned w/o a DPF.

Are you running a tuner with dpf delete tunes?

Is the check engine light on?

If you aren't running a tuner like Spartan or H&S, or at least some sims you can't just delete the DPF. If you are running a tuner and you're still blowing smoke check your coolant level because you might have blown your headgaskets...

X2 a DPF is not like cutting out a cat you need a tuner to remove the DPF function from the computer
